"This is based on an old S.H.I.E.L.D. program."
Holden Radcliffe[src]

The Life-Model Decoy Program was a dismissed S.H.I.E.L.D. project set up to create a Life-Model Decoy, an android designed to act as a safeguard substitute for a S.H.I.E.L.D. agent. The project was eventually picked up and completed by Holden Radcliffe.


The Original Program

"I still can't believe he made a fully functioning autonomous LMD."
"Yeah, put us to shame."
Sam Koenig and Billy Koenig[src]

S.H.I.E.L.D. technicians Eric, Billy and Sam Koenig worked together on the original LMD Program. However, despite the efforts, they never achieved to built a fully functional android. Eventually, the project was abandoned.[1]


Leo Fitz discovers the existence of Aida built by Holden Radcliffe

"Well, you've already met A.I.D.A., digital personal assistant, as a voice on the computer. So, uh, I built her a body."
"Yeah, a naked body!"
Holden Radcliffe and Leo Fitz[src]

The Life-Model Decoy Program was secretly reactivated years later by Dr. Holden Radcliffe, who was cooperating with S.H.I.E.L.D. and had befriended S.H.I.E.L.D. scientist Leo Fitz. Using the LMD program's technology, Radcliffe successfully transferred the data of his personal digital assistant A.I.D.A. into an android body.[2] Radcliffe never disclosed Aida's true nature to anyone but Fitz[3] until he was forced to admit that he had worked on the LMD program without S.H.I.E.L.D. proper authorization.[4]

More and More Androids

A Quantum Brain powering the upgraded Life-Model Decoys

"Everything in the original brain's memories – knowledge, desires – is contained in the Quantum Brains. So, you see, I–"
"You said "brains.""
Holden Radcliffe's LMD and Jemma Simmons[src]

Under the corrupting influence of the Darkhold, Holden Radcliffe and Aida successfully built many LMDs. These notably included androids of Melinda May[5], Phil Coulson, Leo Fitz, Jeffrey Mace, Alphonso Mackenzie as well as several LMDs of Daisy Johnson[6], and a LMD of Radcliffe himself. Unlike Aida, who was running on extremely sophisticated computer programs, these LMDs were functioning with Quantum Brains.[1]
